Saving the best for last: Differential usage of impaled prey by red-backed shrike (Lanius collurio) during the breeding season

Popis výsledku v původním jazyce

We compared the prey composition of the red-backed shrike's (Lanius collurio) larders in agricultural habitats in Italy, France and Poland. This species exhibits the behaviour of impaling prey in larders, a behaviour attributed not only to storing food,but also as a social indication for sexual selection and/or demarcation of territories. A total of 426 impaled items were identified in 244 larders. Most common prey were identified for each country: Insecta (Hymenoptera) in Italy, Amphibia, Insecta (Diptera) and Clitellata in Poland, and Insecta (Orthoptera, Lepidoptera) in France. We found no relationship between type of prey impaled and height of impalement, however, we noted a negative relationship between the height of impalement and the distance to the nearest road. Furthermore, impaled toxic prey were found in all three countries, strengthening the possibility that prey are exposed to expedite the degradation of toxins or used as a social signal. Our results showed that the avera
